NTTE is extremely difficult... it just seems easy because someone posted a step-by-step guide. I would have never found those ghosts or know to not scan Praedyth and to go fight another boss. I'm fine with those guys getting to enjoy those weapons for longer than me. They earned it. Then they were nice enough to post a very easy to follow guide (with vids) to help us out. Totally fine with it. I'll enjoy the other 10 exotics I've gotten through quests while I wait.
